In this paper, we propose a novel V2V transmission scheme, namely S3-RNC (Shuffled Scattered Symbol-level Random Network Coding), for Mobile Content Distribution (MCD) between communication pairs traveling on opposite directions. To cope with the Doppler Effect caused by extremely high relative velocity, symbol-level random network coding (RNC) with shuffling (interleaving) and scattering is used in our proposed scheme. As the second step, receivers, moving together as a cluster, cooperatively relay their received S3-RNC coded blocks, in order to maximize the probability of successful decoding. Our simulation results show that S3-RNC improves throughput performance significantly in high mobility environment. By utilizing S3-RNC, consumer vehicular communication devices are able to provide a lot of useful information to vehicular users.
在本文中，我们提出了一种新的V2V传输方案，即S3-RNC (Shuffled Scattered Symbol-level Random Network Coding)，用于移动内容分发(MCD)。为了应对极高的相对速度所带来的多普勒效应，我们提出的方案采用了带洗牌(交织)和散射的符号级随机网络编码(RNC)。第二步，接收器作为一个集群一起移动，合作中继接收到的S3-RNC编码块，以最大限度地提高解码成功的概率。仿真结果表明，S3-RNC在高移动性环境下显著提高了吞吐量性能。通过利用S3-RNC，消费级车载通信设备能够为车载用户提供大量有用的信息。

We proposed the light field acquisition system using the wedge-shaped waveguide. To obtain the light field reflected from the object, the lens array is mounted on the wedge-shaped waveguide. The light field information is forwarded through the waveguide and captured. In the experiment, we obtained the light field image variant with the object distance.

In a typical recognition system, the inclusion of more training data is likely to increase the recognition rate. However, it is not easy to obtain large training sets. Focusing on practical applicability such as controlling home appliances, we propose a hand gesture recognition method from one example that is computationally efficient and can be easily implemented. 3D hand motion trajectory is achieved from a depth camera and then normalized for translation invariant feature extraction. Based on the simple K-NN classifier, we develop a pattern matching method by combining the DTW (Dynamic Time Warping) algorithm and a statistical measure for similarity between two random vectors. We conducted computational experiments on hand gesture data and compared the results with those derived via conventional DTW recognition.

To match two images with a large scale difference, a scale parameter can be introduced into the warp parameters of the KLT tracker. For some images, the KLT tracker with the scale warp parameter fails to converge. We assume that this result is caused by the singularity of the Hessian matrix. An improved KLT tracker is proposed to avoid this tracking failure. The proposed method introduces an index (scale invariance index) to determine how close the Hessian matrix is to a singular one with the scale warp parameter. According to the index, either of two different sets of warp parameters is selected: one is with the scale warp parameter and the other is without it.

Recently, a healthcare system utilizing electronic technology is attracting attention in the world. People are becoming increasingly conscious about health. Current healthcare services increase health awareness by providing information, but don't utilize the information. Moreover, medical service has problem of lacking the concept of prevention. For those problems, this research proposes a lifestyle improvement support system which shows user how to use advice. At the time of shopping and cooking, the system provides advice that match user's context. By using the context, the system provides proper advice. The previous research found that user's lifestyle is deeply related to the content of advice. In order to solve those problems, this research includes budget, work load, time in advice as context. This research performs a comparative evaluation of the proposed algorithm and the algorithm of the previous paper.

The proposed SUN OFDM-based RF CMOS transceiver, with replacement of ZigBee, can be used as not only an energy saving intelligent green home, which is related to Smart Grid, but also an universal remote controller, a Building Automation, and so on. With our proposed SUN OFDM RF transceiver, wireless connectivity among CEs (Consumer Electronics) devices and electric meters can save electronic energy and make lives more comfortable. The proposed RF transceiver consists of a RF front-end, a TX BBA (Base Band Analog), a RX BBA, and a PLL. Re-using of a LC resonator in the RF front-end can reduce the chip size of RF transceiver, DC power consumption, and the cost. The proposed RF transceiver is implemented in a 0.18-μm CMOS technology and consumes 37-mA in TX and 38-mA in RX mode from a 1.8-V supply voltage. In addition, with a fabricated RF transceiver chip, we have succeeded a public demonstration.

In this paper we present work on exploiting visual temporal masking phenomenon applied to video compression. Our results show that it is possible to reduce bitrate of the compressed video sequence without affecting subjective quality and quality of experience (perceptually lossless). The principles we present here are applicable to all modern hybrid coding systems and can be implemented seamlessly with video delivery platforms. Results show up to 6% of additional savings when implemented on top of the state of the art encoder.

Telematics services are predicted to spread to many more consumers with the increased availability of free telematics smartphone applications. In these telematics services, servers and consumer devices such as smartphones and car navigation terminals have to communicate large amounts of various types of data by uplink and downlink. Finding methods to decrease the data size for communication is one of the most significant issues in this field because of the cost for consumers and service providers. In this paper, we propose a new data compression method for telematics, which deletes redundant data and applies an appropriate compression method for a situation. Moreover, we evaluated our method with the probe data defined by ISO22837 and report positive results.

High Efficiency Video Coding (HEVC) is the next coding standard that is being finalized by ITU's Joint Collaborative Team on Video Coding (JCT-VC). This paper compares the H.264/AVC, current coding standard, and HEVC (aka H.265) in mobile compute environments. In this study, the focus, within the mobile compute environment, are smart phones. The major smart phone elements are smaller screen size, which is typically 3.5 inches diagonal to 5.0 inches diagonal for high end smart phones and typical cellular network bandwidth, which is typically 3G or faster. There is compelling subjective test feedback that indicates human device interaction focused on user's experience is very similar between HEVC and H.264 encoding standards for mobile environment screen size and higher cellphone bandwidth (such as 400kbps constant bit rate). This suggests the benefits of HEVC over H.264 in mobile environment are not as clear.
